Novak Djokovic started the ATP Finals in London with an easy victory. The first Serb placed the first Serb pushed debutant Diego Schwartzman with 6-3, 6-2 on the side.
The Argentine, scaled eighth, had lost the five previous encounters with Djokovic and won no set in their two hardcourt games. Even now Schwartzman did not come close to set wins, although he did break the Serb in the third game. The number one in the world repaired the damage immediately and did not give away any breakpoints in the future.
The 33-year-old Djokovic becomes the oldest winner when he writes the tournament, which is considered the unofficial World Cup, and thus equals the record number of six final victories of the absent Roger Federer who is recovering from an operation on the knee.
Later today, the Russian Daniil Medvedev and the German Alexander Zverev meet in the same group.
